- login.go: keep both new imports (mdm + nbnet + server)
- ios/NetBirdSDK/client.go: additive struct-field merge (mdmLoader + stateMu/connectClient/config)
- setconfig_mdm_test.go: adopt new withMDMPolicy(t, s, policy) signature; fix stray old-signature call in TestSetConfig_MDMAllow_ManagementURLPortNormalized
